I have a RCBS Charge Master 1500 and I like it. I want to load 600 rounds of 204 ruger and want the loads to be very accurate. Question, can and will Harrell"s premium measurer dump a load close to the tolerance of the RCBS. Loading 600 rounds with the RCBS will take quit sometime, so I'm motivated to speed up the process but do not want to loose my accuracy. Any opinions will be appreciated.
thanks for your time. Powder will probably be 4895.

OK, I have both(along with a couple of others-yeah, I am a "collector" of toys) but more to the point If you are looking to increase speed and keep accuracy go with the Harrels, or any drop type-dial it in just under your desired charge and get an Omega trickler to drop the EXACT amount onto your scale.
Since you said accuracy of the load is paramount that is what I would recommend and what I do.

If you were using spherical powders (which you are not) the Harrell's would do that.
You might check a benchrest forum about how well the Harrell's would work with 4895. I know a lot of those shooters load H322 with a Harrell's.

You could speed your operation up by using 2 of the Charge Masters.

I have a older technology in the AMT/Lyman Autoscales. Many people complained they are slow. For the mostly small lots I load one works fine. For larger lots I use 2 Autoscales.
The Autoscale has an Ohaus beam so accuracy is little different than hand weighed scales.

What is the purpose of the 600 rounds?
Just for giggles, why don't you take say 5 cases that are prepped alike and then using a balance beam scale, load you prime load in one and then +1gr in another, then +1 more grain in another and then +1 more in yet another. Also, load a couple going downward from your prime load. Don't mark the cases and shoot them all at one target and see what you get.

I've been reloading for over 50 years now. I have a few powder measures on my bench. If you want ACCURATE loads that are consistent, you need to weigh each charge. The reason being that the VOLUME powder measures rely on the weight of the powder volume ( baffles do help)and how smoothly the powder will fill and not jam the drum causing the drum to "jump" or otherwise cause a vibration that will jar the charge in the drum and add or remove powder grains. That being written, you still can get accurate loads for most shooting. If your shooting under 300 yards,the RCBS type drum measure will work well.
I shoot long range exclusively every weekend.
I shoot a lot of ammo in a month. Like you I did not want to spend a long time weighing out each powder charge. The full-digital measures are just too slow for me. I bought an electric analog balance beam measure that will throw a 50 grain powder charge in 5 seconds. A 100 grain charge in 8 seconds. while the next charge is being dispensed, I charge the previous case and seat the bullet. Once you get the hang of it, you can do over two hundred loaded cases in a hour with out rushing.
There were made in the past very accurate volume powder measures that could throw a charge within a 1/10th of a grain every single time. I still have one made by Belding & Mull. They are expensive when you find one. They are very fast to use. They are a two step measure.Dispense charge into the measuring tube. Then dump into the powder funnel on the mouth of the case.

All depends on the powder. Stick powders I run through a pair of charge masters for increased speed. Harrel I use for ball powders.

I load in a similar way as Rapidrob on my Chargemaster. I used to stand there idle while the Chargemaster measured each charge, place it in the case, then wait for the next one. Now I have greatly sped up the process by loading a bullet into the case just measured, which by the time the next charge is dropped, I am done with loading the bullet and it's on to the next one...

Many thanks to all for your solutions. Always fun to learn new ways of doing things. This is my prairie dog gun will shoot out to 500 yds.

+1

With the charge master on auto mode, the next charge is usually ready by the time I am through seating the bullet.
